Statement of Volatility
Your printer contains various types of memory that can store device and network settings, and user data.
Type of memory Description
Volatile memory Your printer uses standard random access memory
(RAM) to temporarily buffer user data during simple print
jobs.
Non-volatile memory Your printer may use two forms of non-volatile memory:
EEPROM and NAND (flash memory). Both types are used
to store the operating system, device settings, network
information and bookmark settings, and embedded
solutions.
Hard disk memory Some printers have a hard disk drive installed. The printer
hard disk is designed for printer-specific functionality.
This lets the printer retain buffered user data from
complex print jobs, as well as form data, and font data.
Erase the content of any installed printer memory in the following circumstances:
•
The printer is being decommissioned.
•
The printer hard disk is being replaced.
•
The printer is being moved to a different department or location.
•
The printer is being serviced by someone from outside your organization.
•
The printer is being removed from your premises for service.
•
The printer is being sold to another organization.
